“Bones of Contention” is the first nonfiction feature film to explore the theme of historical memory in Spain, focusing on the repression of lesbians and gays under Franquismo. Lining the roads of Spain, masked by miles and miles of pine trees, are unmarked graves in which over a hundred twenty thousand victims of the Franco regime are buried. Today the families of the desaparecidos lead a grassroots effort to uncover and identify the bones of their loved ones, despite opposition from the Spanish government. Invisible to the eye but hyper-visible in the mind, these mass graves of Spain’s missing persons are an apt metaphor for the historical memory conundrum.
